AA potential diamond top

Preceeding uptrend was very clean and strong, than topping volatility came in and formed what seems to be a diamond top ready for reversal. Entry on the break of the diamond or a breakdown below 15. Possible support zones around 15 and then 13 and 12. The diamond price target would bring it right into the longterm . 618 retracement . RSI seems to be breaking lower thus staying in bearish territory. Short interest at 3 % shouldn't be a problem.
